Resilience: also known as resilience, or impact elasticity, elasticity, is also an important performance indicator to measure rubber elasticity. With the pendulum at a certain height of impact rubber, the ratio of the height of the rebound and the original height is called the rebound rate, expressed as a percentage (%), the greater the value, the higher the elasticity of rubber.   Tear permanent deformation: referred to as permanent deformation, is also an important indicator to measure rubber elasticity. After the rubber is stretched and broken, it is parked for a certain time (usually 3 minutes), and the ratio of the increased length of the deformation part to the original length is expressed as a percentage (%). The smaller the straight, the better the elasticity of the rubber. In addition, the elasticity of rubber can also be measured by compression permanent deformation.   Fixed elongation strength: also known as fixed elongation strength. It refers to the force required per unit area when the rubber is extended to a certain length, that is, when it is extended to 100%, 200%, 300%, 500%. In terms of N/cm2. This is an important mechanical index to measure the strength and toughness of rubber, the greater the value, the better the tolerance of rubber, indicating that this rubber is not easy to produce elastic deformation.

How is the anti-skid performance of silicone products? Silicone products play an increasingly important role in our daily life, and its excellent physical and chemical properties make it widely used in many fields. Among the many features, the anti-skid performance of silicone products is particularly outstanding, which brings great convenience to our lives.   First of all, the anti-skid performance of silicone products is mainly due to its unique surface structure. The surface of silica gel is composed of tiny bumps and grooves, and this structure allows the silica gel to form a tiny "suction cup" effect when it comes into contact with an object. When the silicone product is in contact with the surface of the ground or other objects, these tiny bumps can be embedded into the tiny depression on the surface of the object, thereby increasing the contact area and improving the friction. This "sucker" effect makes silicone products not easy to slide when subjected to external force, thus showing good anti-slip performance.   Secondly, the anti-skid performance of silicone products is also related to its excellent elasticity. Silica gel has good elasticity and can quickly recover its shape, which makes silica gel products quickly adapt to the shape of the surface of the ground or other objects when subjected to external force, forming a closer fit. This tight fit can further improve the friction between silicone products and the surface of the object, thereby enhancing its anti-slip performance.   In addition, the anti-skid properties of silicone products are also affected by their adhesion properties. Silica gel has excellent adhesion properties and can be quickly attached to different surfaces. When the silicone product is in contact with the surface of the ground or other objects, the small bumps on the surface can be fully attached to the surface of the object, forming a strong adhesion force. This adhesive force can effectively prevent silicone products from sliding when subjected to external force, so as to further improve its anti-skid performance.   The anti-skid properties of silicone products have been widely reflected in practical applications. For example, silicone anti-slip pads are popular with consumers because of their excellent anti-slip properties. Whether used at home or in public places such as offices and restaurants, silicone anti-slip MATS can effectively prevent items from sliding or falling, bringing great convenience to our lives. In addition, the silicone conveyor belt is also widely used in industrial production because of its high friction coefficient and excellent anti-slip performance, to ensure the stability of the material in the conveying process.

Toys are often used as a way to decompress entertainment in today's society, whether adults or children, and toys are usually objects to play with. Of course, the variety of toys is also very much! I believe that friends also have a certain understanding, today I will introduce a silicone toy, silicone material made of natural rubber extracted from silicone toys, and high temperature and cold resistance, generally in -60~250℃ to maintain good elasticity, thermal oxidation and ozone with high stability!   What are the characteristics and advantages of toys made of silicone from the material 1. Because silicone is a natural rubber (also known as silicone), the first advantage of the material is that it is non-toxic and harmless, and will not produce harmful substances to the human body. 2. Because silicone toys are often vulcanized at high temperatures in the production process, they have high temperature resistance, and high temperature resistance is 220 degrees. Silicone raw materials have many advantages, such as: low temperature resistance -40 degrees, insulation, green environmental protection and so on! The above two points are mainly reflected in the manufacture of toys.   Silicone toys are recreational items to accompany us, long-term use we must clean, silicone toys can be washed with boiling water and effective disinfection, do not have to worry about the toy itself will be bad. Silicone toys have colorful and beautiful colors, I believe that everyone is obvious to see. Many silicone products on the market are very bright colors, very durable, such as silicone bags, silicone crash pads. Silicone has the characteristics of long life, anti-itch in the air, non-volatile because the life is very long, not to say 10 years and 20 years of life, from the birth of the first child to the birth of five years, to the birth of the second child can continue to play these silicone toys, the color will also be beautiful.   Silicone toys usually use soft materials, fairy clear silicone raw materials will not cause harm to children's skin. For example, the same toy is made of two materials, silicone and plastic. There may be a little raw edge on the toy, but the silicone material this edge will not hurt the baby, and the plastic is usually very hard, so it may be cut into the baby. A variety of colors to provide choices, many babies are curious about the world, the baby will like a variety of colors at this time, as the baby grows up, may be only a few colors. So choosing a variety of colors is also a good choice.

When testing rubber products, it is not only necessary to test the high temperature resistance and cold resistance of rubber, but also to test its point resistance. Perhaps in the impression of most people, rubber is insulating, but this is not the case, some rubber also has electrical conductivity, so it is also very important to do a good job of insulation and chemical inertness detection. The application range of rubber is very wide, in the electrical and electrical industry is also more common, as a special insulating material, rubber also needs to have anti-ultraviolet and anti-ozone properties, so as to better meet people's needs, in general, conductive rubber is a variety of conductive particles dispersed in rubber made of elastic conductive materials, in its detection, We must pay attention to whether the electrical performance meets the corresponding standard requirements. In addition, the testing of rubber products also includes weather resistance and aging resistance, to ensure that rubber products do not have any pollution and harm to the environment, so that rubber products can achieve sustainable development.

General silicone rubber products and metal adhesion is not good, are required to be treated on the metal surface   1, metal surface treatment: In order to obtain the best bonding effect, the metal surface must be clean and pollution-free. With 200-400 micron steel sand or brown corundum for sandblasting treatment, until the metal surface is gray.    2. After sandblasting, degreasing with solvent to remove grease. Cold rolled steel is usually treated with steel sand, stainless steel, aluminum, copper, etc., with brown corundum (aluminum oxide). Phosphating can also be used.    

Silicone products need to do what test items, silicone products are widely used in modern life, from kitchen utensils to electronic products accessories, almost everywhere. Silicone is a very safe material, however, in order to ensure its quality and safety, it is still necessary to carry out comprehensive and detailed testing of silicone products, which is a crucial link to understand what testing items silicone products need to do.   Testing the physical properties of silicone products is a basic and critical step. This includes testing its hardness, tensile strength, compressive permanent deformation rate, tear strength, etc. These physical properties directly affect the service life and user experience of silicone products. For example, hardness determines the flexibility and feel of silicone products, while tensile strength and tear strength are related to its durability and damage resistance.   The detection of chemical properties is also important for silicone products. This includes assessment of heat, cold, chemical and weather resistance. These properties determine the stability and durability of silicone products under different environmental conditions. For example, food-grade silicone products need to undergo rigorous heat resistance tests to ensure that they do not release harmful substances at high temperatures.   For some silicone products for specific purposes, special testing may also be required. For example, silicone products that need to come into contact with food need to be certified by the FDA (US Food and Drug Administration) to ensure their safety. For silicone products that need to conduct electricity or insulation, corresponding electrical performance testing is required.   In addition to the routine testing items mentioned above, for some silicone products with complex structures or special functions, more in-depth testing may be required. For example, for silicone products containing a metal skeleton or embedded with other materials, X-ray testing is required to ensure the integrity of its internal structure. For silicone products that need to be sealed or leak-proof, pressure and air tightness testing are required.   Why such a comprehensive test? The answer is simple: quality and safety. Comprehensive and detailed testing can ensure that silicone products can maintain excellent performance and safety under various environmental and use conditions. This not only helps improve the user experience, but also avoids security problems caused by product defects.   Comprehensive and detailed testing of silicone products is a necessary means to ensure its quality and safety. From physical properties to chemical properties, to special uses and in-depth testing, each test is related to the practical application effect and safety of silicone products.

There are consumers who buy silicone products and find that there is a phenomenon of breakage on the edge, which often troubles many friends and leads to a certain cognitive requirements for silicone products, less a certain purchase rate, and for silicone products edge damage phenomenon is not helpless. Silicone products edge damage in the silicone products industry is called "edge explosion" the main reasons are caused by several phenomena, the product in the process of use due to the serious force and the impact of the mold caused dislocation phenomenon, so that the silicone products have minor damage resulting in subsequent gradually wear. Secondly, the product itself is damaged, in the production and processing of silicone manufacturers due to the temperature and material fixed-line problems caused by product damage phenomenon, in addition to the hardness and curvature of the product shape also has a certain impact, so the product damage problem can be controlled in various aspects of the cause!   1, hardness problem, low hardness silicone products bursting edge is more common, the main phenomenon of low hardness is the parameter deployment of silicone products manufacturers, such as the temperature of the machine and secondary exhaust problems, so set the parameters of the machine is very important, the temperature is reduced, the vulcanization time is reduced, the molding processing time of the product is just controlled in the stage of curing completion. If the time is too long, there will be material expansion of the raw material in the machine, resulting in the separation of the parting position leading to rupture.   2, raw materials are the key to silicone products, if the raw materials in the production process is not mixed in accordance with a certain time or the added part of the additives are insufficient, it may lead to various problems in the production process of the product, such as edge explosion, poor fluidity, product bulge and deformation.   3, the structure is more complex, the product explosion damage phenomenon is also relatively large, in addition to hardness, usually silica gel products explosion phenomenon in the case of low hardness with the product structure has a great relationship, such as the product is relatively thick, there is a certain arc and parting position at the high point of the product, so in the product design at the same time need to strictly control its parting position.   4, the mold is the key to the edge damage of silicone rubber products, in the mold development at the same time, how to butt inconsistent with the upper and lower parting point dislocation phenomenon, then production The problem of product damage has not been solved, so the mold processing needs to be strictly controlled.   5. Other reasons Some exceptional factors can also cause the product to explode, such as: The weight of the rubber material is not well controlled (too heavy will cause the product to explode, too light will cause the product to lack of material, lack of corners, so control in a reasonable weight will reduce the probability of explosion) Secondly, in the long-term production process without intermittent conditions should be reduced mold temperature, Keep the mold in a certain temperature range, etc. (Spray the mold with water to maintain the temperature of the mold properly without intermittently).
